The Creator, Bless be He, started the creation of the world by defining two types of systems. The concealed, which is the heavens and the revealed, which is the earth.

It is coded in the word “In the beginning” בראשית. Theב is the two heads that come from ראשית, which is the source of Light for the world. It is the beginning that represents the thought of the creator where there is no separation or difference in the light.

The first letter of the Torah and the story of creation ב , represents the duality and the paradox of this world. Everything comes from one and undifferentiated state of light and consciousness to form two systems, opposite to each other. Heaven and earth, Light and darkness, soul and body. א and ת. (The Alef begins with a concealed dot above it)

This secret of the hidden unity is in the Tetragramaton, which is the code name for the system that rules the world that is created for us. The numerical value is 26, which is split to two aspects, the concealed YH and the revealed VH.

26 = 13 + 13.
13 = One = אֶחָד.
26 = אֶחָד + אֶחָד = 2 = ב

The code for merging the two systems into one is in Zechariah 14:9

“בַּיּוֹם הַהוּא, יִהְיֶה יְהוָה אֶחָד–וּשְׁמוֹ אֶחָד”
“On that day YHVH will be ONE and his name ONE”
